DETACHABLE CALK FOR HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 818,939, dated June 2, 1885.

Application filed December 13, 1884. (No model.)

To all whomit HMZZ/ concern:

Be it known that I, J ACOB A. ALLEN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Detachable Calks, of which the following is a specification, reference be ing had therein to the accompanying drawings.

Myinvention comprises a novel construction of those detachable calks which are capable of being temporarily applied to horseshoes, so as to afford a secure foothold for the animal in slippery weather.

The present device consists, essentially, of a spring-plate adapted to bear wholly and directly against the under side of the shoe, and extending about from the toe to the heel of the same, or, in other words, said device is applied to what is commonly known as the quarter oftheshoe. This spring-platehas near its front end a downwardly-projecting toe-call; and a pair of upwardly-projecting clips, one of the latter being adapted to grasp the outer edge of the shoe, while the other clip fits snugly against the inner edge of the same. The rear end of the spring-plate has a downwardly-projecting heel-call; and a single upwardly-proj ectin g clip, which latter grasps the outer edge of the shoe. Furthermore, this plate is so constructed as to cause its rear portion to spring inwardly, or toward the center of the animalsfoot, in order that the heelclip of the device may be clamped very firmly against the outer edge of the shoe as soon as said plate is sprung outwardly asufficient distance to allow this clamping action to be effected, as hereinafter more fully described.

Another feature of my invention consists in providing the upper surface of this springplate with one or more longitudinal ridges capable of embedding themselves in the under side of the shoe when said plate is properly applied to the latter, as hereinafter more fully described.

In the annexed drawings, Figure 1 is a side elevation of one of my detachable calhs. Fig.

2 is a plan of the upper surface of the same. Fig. 3 is a plan of an ordinary horseshoe with one of my detachable calhs fitted thereto and another plied.

call; applied to a shoe. Fig. 5 isa transverse section of the shoe and attached calk.

The principal member of my device is a plate or bar, A, made of spring metal and of such a shape as to correspond with the curvature usually given to the quarter of a horseshoe. Projccting upwardly from the extreme front end of this spring-plate is a toeclip, B, adapted to grasp the outer edge of the shoe, an intermediate clip, (3, being located somewhat in the rear of clip B and on the opposite side of said plate. This intermediate clip, 0, is arranged to grasp the inner edge of the shoe. Projecting downwardly from the aforesaid plate is a toe-calk, D, disposed in any position that will be the most eliective, or the best adapted to the horses feet. The rear end of plate A has a downwardly-projecting heelcalk, E, and an upwardly-projecting heelclip, F, which clip is adapted to grasp the outer edge of the shoe. Furthermore, the upper surface of plate A has, preferably, two longitudinal or marginal ridges, G G, capable of embedding themselves in the under surface of the shoe, as seen in Fig. 5.

H is an ordinary horseshoe, having atoeprojection, I, and apair of heel-projections, J J, although the application of my call: is not intended to be limited to this or any other special form of shoe.

The method of applying the device is as follows: The plate A must be manufactured with reference to the size and style of shoe to which it is to be subsequently fitted, in order that the rear end of said plate will naturally spring inward, as seen at the right side of the shoe in Fig. 3. The front portion of the device is then applied to the shoe,so as to cause the toeclip B to grasp the outer side of the shoe and near its toe-projection I, while the intermediate clip, C, embraces the inner edge thereof.-

Sufficient leverage is now exerted against the rear portion of said plate to spring or bend it outwardly until the heelclip F snaps over the external edge of the shoe, which act completes It is evident the spring-plate A acts in such a manner as to cause the various clips to be clamped very tightly against the edges of the shoe, thereby retaining the device in its proper place, and enabling the horse to get a safe foothold by means of the ICO calks D and E, which may be sharpened in any approved way. In some cases, however, it may be advisable to use the ridges G G for the purpose of assisting the spring in retaining the device in place; but whether these ridges are used or not it will be noticed by referring to Figs. 4 and 5 that the upper surface of the device fits snugly against the under side of the shoe. Consequently there is no opportunity for pebbles and other obstructions to enter between the plate and shoe, and

thus force the device away from its proper bearing and cause it to become detached.

To detach the device, the heel-clip F is driven down until it quits its grasp against the edge of the shoe, at which moment the plate A springs back to its normal position, thereby rendering it an easy matter to disengage the other clips B C.

As the right and left calks are separate and distinct devices, not being connected in any manner whatever, it is apparent that either one of them can be used alone, or that either of said calks can be removed from the shoe without disturbing the other calk.

I am aware it is not new to apply calks to a spring-plate which is fitted edgewise within the inner margins of a horseshoe, and has a member extending across the toe thereof, for the purpose of connecting the two curved portions of said plate and rendering the device a complete and undivided unit, as such a construction is seen in the patent granted to R. J. Bartley, December 17, 1878. As distinguished from this device, the fiat side of my spring-plate bears directly against the under side of the quarter of the shoe, and the calks on the oppositequarters are not connected by a member running across the toe of the shoe, thereby enabling me to use one calk alone, or to remove either calk without disturbing the other.

- I claim as my invention- 1. A detachable horseshoe-calk consisting of the plate A, which springs inwardly toward its rear end, and is provided with a toe-clip, B, intermediate clip, C, heel-clip F, toe-call: D, and heel-call: E, which clips grasp the edges of a shoe in the manner described, and the upper or extended surface of said plate bears directly and wholly against the under surface of the quarter of the shoe, the plate A being made without any connecting portions at the toe, in order that the calk-plate on one side of the shoe may be separate and distinct from the calla-plate on the other side thereof, thereby permitting either of said calkplates to be removed without disturbing the other, "as herein explained.

2. As a new article of manufacture, a detachable calk consisting of the spring-plate A, provided with upwardly-projecting clips B C F, downwardly-projecting calks D E, and one or more longitudinal ridges, as G, on the upper surface of said plate, as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB A. ALLEN.
